Application filed May 21,1906. Serial No. 318,021.

To all whom it may concern.-

Be it known, that I, CARL WILMsHo ER, manufacturer, a subject of theKing of Prussia, residing at Erfurt, Kingdom of Prussia, German Empire,have invented certain new and useful Improvements in stiffening-Caps forShoes, of which the following is a specification.

My invention relates to improvements in stiffening cap for shoes.

The characteristic feature of the stiffening cap for shoes according tothis invention consists in the fact that the material of the cap ispartly penetrated by a layer of rubber placed on it. In this way, thecap, on the one hand, remains elastic and flexible, and, on the otherhand, has sufficient stifiness and therefore retains permanently theshape given to it. The rubber layer, partly penetrating the material ofthe cap, also enables pl llaiyer of canvas to be put on and securely Twodifferent constructions of the cap according to this invention areillustrated in the accompanying drawing.

Figures 1 and 2 are respectively an elevation and cross-section of oneconstruction, and Figs. 3 and 4 an elevation and cross-section ofanother construction.

The leather 1 is provided with a number of perforations 2 through whichpasses therubber layer 3. The side of the leather 1 opposite the rubberlayer 3, is provided with a canvas backing 4 which is secured in areliable manner owing to the connection with the rubber layer 3 passingthrough the openings 2 of the leather 1.

The construction in Figs. 3 and 4 is similar to that shown in Figs. 1and 2, only the leather 1 is cut out at the back at 5, so that theleather portion has the form of an arc. At the part where the leather iscut away, the corresponding portion of the cap is consti tuted by therubber layer 3 and the canvas layer 4. The openings 2 are arranged inthe leather 1 in the same way as in the construc tion shown in Figs. 1and 2.

It is immaterial what size and shape is given to the cap.

What I claim is:

A stifiening cap for shoes comprising a perforated stiffening member andan elastic member having flexible projections extending into saiddperforations, and a backing secured to sai stifiening member andprojections.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
